Table 3 Estimated prevalence of low SM, low HS, low GS and sarcopenia in different age groups and the elderly

From: Estimation of prevalence of sarcopenia by using a new bioelectrical impedance analysis in Chinese community-dwelling elderly people

  Age group (year) Number Low muscle mass Low gait speed Low handgrip strenth Sarcopenia
Male 60–64 146 40 (27.4) 4 (2.7) 5 (3.4) 4 (2.7)
65–74 199 68 (34.2) 9 (4.5) 4 (2.0) 8 (4.0)

  1. Low muscle mass was defined as appendicular skeletal muscle mass index (ASMI) <7 kg/m2 for males and <5.7 kg/m2 for females; low gait speed (GS) as GS <0.8 m/s; low handgrip strength (HS) as HS <26 kg for males or <18 kg for females. Using Pearson chi-Square tests or Fisher exact test (for which an expected cell count was <5) for categorical variables. Comparison between 60-64, 65-74, and ≥75, p < 0.05 was considered statistically significant
